This square sketchbook has a really satisfying, premium feel. The cover is a hardbound faux PU leather that looks and feels great. It's held shut by an elastic band to keep your pages safe. Inside, you get 128 blank pages (64 sheets) of thick, 180 GSM bamboo paper. The paper is smooth, bright white, and holds up really well to most dry media like pencil, charcoal, colored pencil, and even light marker or watercolor – it's ink-proof, so bleed-through is minimal. The book is thread-bound, which means it lays completely flat when open, giving you the full page to work on. Handy extras include two ribbon bookmarks and an expandable pocket on the inside back cover for storing loose notes or inspiration. The square 8x8 inch format is a nice change from rectangles and is perfect for sketches, doodles, planning, or journaling.
